Yes. For the Internet connection on the AE "Shared Public Ip addresses" selected and for connecting to the SH tried DCHP and a fixed address. All were tried with re=booting AE in each case. The SH and AE had been powered down and re-started as well. No green light, yellow flash with indication of cannot connect to internet. With other settings it complained about start and end address of DCHP. Perhaps my use of DMZ had not cleared from both devices so have tried factory reset on both but have ended in the same situation so returned to DMZ. Seems strange that I can navigate around all the pitfalls and settings of DMZ but cannot manage a simple connect to the SH. Thanks for your ideas as I bet in the end it may be something easily overlooked in the AE.
